For solving the problems of the technologies described above, an aspect according to the utility model provides a kind of balance suspension, comprising: a plurality of first propelling rods; A plurality of second propelling rods; Jackshaft; Back axle; Strut mount, strut mount connects to ground; Leaf spring, first end of leaf spring is connected with jackshaft, and second end of leaf spring is connected with back axle; Leaf spring is connected with strut mount; Strut mount is connected with jackshaft through at least one first propelling rod, and strut mount is connected with back axle through at least one first propelling rod; Vehicle frame is connected with jackshaft through at least one second propelling rod, and vehicle frame is connected with back axle through at least one second propelling rod.
Further, first propelling rod is straight.
Further, second propelling rod is a vee-type.
Further, the number that connects second propelling rod of vehicle frame and jackshaft is two, the two second V-shaped settings of propelling rod.
Further, the number that connects second propelling rod of vehicle frame and back axle is two, the two second V-shaped settings of propelling rod.
Further, the junction of second propelling rod and jackshaft or back axle is respectively arranged with the pad at the angle of inclination that is used to regulate second propelling rod.
Further, balance suspension also comprises spring carrying block and saddle clamp, and leaf spring and spring carrying block couple together through saddle clamp.
Further, balance suspension also comprises the cover plate that is arranged between leaf spring and the saddle clamp.
Further, first propelling rod is arranged on the downside of leaf spring.
Further, second propelling rod is arranged on the upside of leaf spring.
Another aspect according to the utility model provides a kind of car hosit, comprises balance suspension, and this balance suspension is above-mentioned balance suspension.
The utility model utilizes first propelling rod and second propelling rod, makes leaf spring no longer bear lateral loading, and makes vehicle bridge side travel can not take place, and has avoided the abnormal tyre wear problems.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 has schematically shown the front view of balance suspension of the prior art;
Fig. 2 has schematically shown the birds-eye view of balance suspension of the prior art;
Fig. 3 has schematically shown the front view of the balance suspension in the utility model; And
Fig. 4 has schematically shown the birds-eye view of the balance suspension in the utility model.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As an aspect of the utility model, the utility model provides a kind of balance suspension.Like Fig. 3 and shown in Figure 4, the balance suspension in the utility model comprises: a plurality of first propelling rods 6, a plurality of second propelling rod 9, jackshaft 1, back axle 2, strut mount 4 and leaf spring 5.Wherein, strut mount 4 is connected with vehicle frame 3; First end of leaf spring 5 is connected with jackshaft 1, and second end of leaf spring 5 is connected with back axle 2; Leaf spring 5 is connected with strut mount 4; Strut mount 4 is connected with jackshaft 1 through at least one first propelling rod 6, and strut mount 4 is connected with back axle 2 through at least one first propelling rod 6; Vehicle frame 3 is connected with jackshaft 1 through at least one second propelling rod 9, and vehicle frame 3 is connected with back axle 2 through at least one second propelling rod 9.When the load that receives from vehicle frame, the leaf spring of the balance suspension in the utility model can rotate around bearing pin 15, thereby realizes the load equalization of jackshaft and back axle.Because the leaf spring place in the left and right sides of vehicle bridge is provided with first propelling rod, and in the position of axle center second propelling rod is installed, therefore; When vehicle bridge was born side force, this side force was born by second propelling rod, at this moment; Side travel can not take place in vehicle bridge, therefore, can not cause tire generation side travel; Thereby avoided consequently and between the tire vehicle frame moving the phenomenon of interference, thereby solved the abnormal tyre wear problems because bigger displacement takes place tire.In addition, can realize the lateral register of vehicle bridge, eliminate assemblage gap on the one hand, form the vehicle bridge location of rigidity through first, second propelling rod, make under extremely abominable road conditions, can not take place yet the vehicle bridge dislocation and with the vehicle bridge relevant fault that misplaces; On the other hand, make leaf spring no longer bear side force, improved the action length of leaf spring, load and rigidity are complementary, reduce the stress of leaf spring, the service life of having improved leaf spring.In addition, the balance suspension in the utility model does not use parts such as equalizing bar and thru shaft, has alleviated the weight (for example, can make about the weight saving 100kg of whole suspension system) of whole suspension system.Preferably, first propelling rod 6 is arranged on the downside of leaf spring 5.Preferably, second propelling rod 9 is arranged on the upside of leaf spring 5.
Preferably, first propelling rod 6 is straight.Preferably, second propelling rod 9 is vee-types.As the mode that another kind is implemented, the number that connects second propelling rod 9 of vehicle frame 3 and jackshaft 1 is two, two second propelling rod 9 V-shaped settings; The number that connects second propelling rod 9 of vehicle frame 3 and back axle 2 is two, two second propelling rod 9 V-shaped settings.Therefore,, can bear side force well, make leaf spring side travel can not take place through second propelling rod of this V-arrangement or second propelling rod of V-arrangement setting.
Preferably, the junction of second propelling rod 9 and jackshaft 1 or back axle 2 is respectively arranged with the pad at the angle of inclination that is used to regulate second propelling rod 9.In the time need adjusting to the length of second propelling rod 9; Can use this pad; Thereby an end that makes second propelling rod 9 to reduce the angle of inclination of second propelling rod 9, has promptly been increased the connected length of second propelling rod 9 on the horizontal direction of vehicle by bed hedgehopping; Reach the purpose of regulating second propelling rod 9, reduced the vehicle frame welding precision the vehicle bridge location influence.
Preferably, balance suspension also comprises spring carrying block 7 and saddle clamp, and leaf spring 5 and spring carrying block 7 couple together through saddle clamp.Especially, balance suspension also comprises the cover plate 8 that is arranged between leaf spring 5 and the saddle clamp.Use cover plate 8 can regulate the gap between leaf spring and the spring carrying block.
As another aspect of the utility model, the utility model provides a kind of car hosit.This car hosit comprises balance suspension, and this balance suspension is the balance suspension among above-mentioned each embodiment.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
